Based on the theoretical studies in Refs. [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]},
\(\eta _1(1855)\)  can be interpreted as a \(\bar{s}sg\)  hybrid meson, a compact tetraquark state, and a \(K\bar{K}_1\)  molecular state, respectively.
Since the photoproduction processes is very helpful to distinguish which inner structure of \(\eta _1(1855)\)  state is possible, we suggest
experimentally searching for \(\eta _1(1855)\)  in the \(\gamma {}p\rightarrow \eta _1(1855)p\)  reaction. With the scattering amplitudes of the
\(\gamma {}p\rightarrow \eta _1(1855)p\)  reaction obtained in the previous section, the differential cross section in the center of mass (c.m.) frame
for the process \(\gamma {}p\rightarrow \eta _1(1855)p\)  can be calculated [9]}
\(\frac{d\sigma }{d\cos \theta }=\frac{m_N^2}{32\pi {}s}\frac{|\vec{p}^{ c.m}_3|}{|\vec{p}^{ c.m}_{1}|}\sum _{s_1,s_2,s_3,s_4}|{\cal {M}}^{i}|^2,\)
